Compost Tumbler with A-Frame Base

This is not the typical “T-Post” DIY tumbler! When it’s full, a compost barrel can weigh up to 440 pounds, and this tumbler’s A-frame base is super sturdy.

The design of the legs make this compost tumbler wheelbarrow friendly, allowing the wheelbarrow to tuck under the barrel. Now, emptying the compost doesn’t have to be a messy job.

Sifting, sorting and screening the finished compost just got a lot easier too! Check out the DIY Shaker Table Project.
New for this project is a comprehensive Plans & Tutorial PDF you can download! Tutorial includes pictorial lists of materials, supplies and tools to complete this project along with schematics showing where these components are used. Each step is explained in detail with diagrams and photos to make it easy to follow, allowing you to build a project you can be proud of!

The problem:

The DIY compost tumbler plans and how-to videos found online are usually based on a T-post design, with the legs in the shape of an inverted “T”.  The problem with that type of base is that they are not very stable, especially when turning a barrel that may weigh over 400 pounds!

T-post bases can be made more stable, but increasing the size of the base comes at the cost of making it difficult to get a wheelbarrow close enough to the barrel. The result is that emptying the tumbler can quickly become a big mess. 

It’s easier to get the wheelbarrow under the barrel!

The solution:

Making an A-Frame design with a criss-cross base was the answer. A Tumbler with a Twist!

This base is super strong and can easily support a heavy compost load. The heavier the load, the more the tumbler “plants its feet” and becomes even more steady.

Best part is that “doing the Limbo” and getting a wheelbarrow to go low enough under the barrel is a piece of cake!

The video below shows the steps in detail to make this compost tumbler, and NEW for this project is a FREE comprehensive Plans & Tutorial PDF.
